Methods of making a laminated glazing having reduced optical distortion when installed in a vehicle are described. The laminated glazing has first and second sheets of glazing material each separately shaped between a pair of shaping members that are then laminated together. The position for bending the first sheet of glazing material may be deliberately offset from the position for bending the second sheet of glazing material. During the lamination step, the first sheet of glazing material may be displaced relative to the second sheet of glazing material by a lateral and/or longitudinal positional displacement. The first and/or second sheet of glazing material may have been cut such that after lamination at least a portion of the peripheral edges thereof are aligned. Apparatus for shaping a sheet of glazing material for carrying out the aforementioned methods is also described, as is a resulting laminated glazing.
A method of making a laminated glazing comprising the steps:
A method of manufacturing a laminated glazing comprising:
A method of manufacturing a laminated glazing comprising:
Apparatus for shaping a sheet of glazing material, in particular a glass sheet, the apparatus comprising:
A laminated glazing comprising at least two sheets of glazing material (a first sheet of glazing material and a second sheet of glazing material), joined by an interlayer structure comprising at least one (a first) sheet of adhesive interlayer material, the first sheet of glazing material, the second sheet of glazing material and the first sheet of adhesive interlayer material each having a first major surface and a second opposing major surface, the laminated glazing being configured such that the second major surface of the first sheet of glazing material faces the first major surface of the first sheet of adhesive interlayer material, and the first major surface of the second sheet of glazing material faces the second major surface of the first sheet of interlayer material, there being an Imprint on at least a portion of the first major surface of the first sheet of glazing material and substantially the same imprint on at least a portion of the first major surface of the second sheet of glazing material, wherein when viewed at zero angle of incidence to the radius of curvature of the first sheet of glazing material, the imprint on the first major surface of the first sheet of glazing material is offset from the imprint on the first major surface of the second sheet of glazing material.
